Specific sciences that participate in the study of life focus more narrowly on certain taxa or levels of observation—e. Although the scientists, technicians, and others who participate in studies of life easily distinguish living matter from inert or dead matter, none can give a completely inclusiveconcise definition of life itself.

Part of the problem is that the core properties of life—growth, change, reproduction, active resistance to external perturbation, and evolution —involve transformation or the capacity for transformation. Living processes are thus antithetical to a desire for tidy classification or final definition.

To take one example, the number of chemical elements involved with life has increased with time; an exhaustive list of the material constituents of life would therefore be premature.

Nonetheless, most scientists implicitly use one or more of the metabolic, physiological, biochemical, genetic, thermodynamic, and autopoietic definitions given below. Living systems are objects with definite boundaries, continually exchanging some materials with their surroundings but without altering their general properties, at least over some period of time.

However, there are exceptions. There are frozen seeds and spores that remain, so far as is known, perfectly dormant. At low temperatures they lack metabolic activity for hundreds, perhaps thousands, of years but revive perfectly well upon being subjected to more clement conditions.

Similar reactions, incidentally, occur in animals and plants. Flames also have a well-known capacity for growth. These facts underscore the inadequacy of this metabolic definition, even as they suggest the indispensable role of energy transformation to living systems.

Physiological Physiological definitions of life are popular. Life is defined as any system capable of performing functions such as eating, metabolizing, excreting, breathingmoving, growing, reproducing, and responding to external stimuli.

But many such properties are either present in machines that nobody is willing to call alive or absent from organisms, such as the dormant hard-covered seed of a treethat everybody is willing to call alive.

An automobile, for example, can be said to eat, metabolize, excrete, breathe, move, and be responsive to external stimuli.

General features

A visitor from another planet, judging from the enormous number of automobiles on Earth and the way in which cities and landscapes have been designed for the special benefit of motorcars, might well believe that automobiles are not only alive but are the dominant life-form on the planet.

If depressed at least twice, thin pressure-sensitive hairs in the trap stimulate the lobes to clamp tightly over an insect. In many respects, this is more satisfying than the physiological or metabolic definitions of life.

However, even here there are counterexamples. Viruslike agents called prions lack nucleic acids, although the nucleic acids of the animal cells in which they reside may be involved in their reproduction.

Ribonucleic acid RNA molecules may replicate, mutate, and then replicate their mutations in test tubes, although by themselves they are not alive. Furthermore, a definition strictly in chemical terms seems peculiarly vulnerable. It implies that, were a person able to construct a system that had all the functional properties of life, it would still not be alive if it lacked the molecules that earthly biologists are fond of—and made of.

Genetic All organisms on Earthfrom the tiniest cell to the loftiest treesdisplay extraordinary powers. They effortlessly perform complex transformations of organic molecules, exhibit elaborate behaviour patterns, and indefinitely construct from raw materials in the environment more or less identical copies of themselves.

How could systems of such staggering complexity and such stunning beauty ever arise? A main part of the answer, for which today there is excellent scientific evidence, was carefully chronicled by the English naturalist Charles Darwin in the years before the publication in of his epoch-making work On the Origin of Species.

A modern rephrasing of his theory of natural selection goes something like this: Hereditary information is carried by large molecules known as genescomposed of nucleic acids. Different genes are responsible for the expression of different characteristics of the organism.

During the reproduction of the organism, the genes also replicate and thereby pass on the instructions for various characteristics to the next generation.A pre-entry assessment of every confined space job is imperative to ensure worker health and safety.

This assessment must include atmospheric monitoring and a visual inspection of the area around the entry point. among service intangibility, cultural factors, and entry mode selection.
